DOUBLING- SPOOLER.

SPECIFICATION forming part of Letters Patent No. 310,722, dated January13, 1885. Application filed October 23, 1888. (N0 model.)

To all whom it may concern.-

Be it known that I, LEONARD V. RICHMOND, of Sand Lake, in the county ofRensselaer and State of New York, have invented certain new and usefulImprovements in Doubling-Spoolers, of which the following is a full,clear, and exact description.

Reference is to be had to the accompanying drawings,forming part of thisspecification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1, Sheet 1, is a front elevation of a portion of a machineembodying my improve ment, the spools being shown in section. Fig. 2,Sheet 2, is a sectional side elevation of the same,taken through thebroken line 00 m, Fig. 1. Fig. 3, Sheet 2, is a sectional side elevationof the same, takenthrough the line 3 y y 3 Fig. 1. Fig. 4, Sheet 2, is asectional plan view of a part of the same, taken through the line 2 2,Fig. 2.

The object of this invention is to facilitate the doubling of yarn uponupright and drum spoolers from cops, spools, and bobbins by providing amechanism that will stop the re ceiving-spool automatically should oneof the threads break or one of the spools become empty, and thus preventa single thread from being wound upon the said receiving-spool, therebyeconomizing time and preventing waste of material.

The form of spooler known as a drumspooler is that shown in the presentapplication, where the receiving-spool is rotated by the drum. Theupright spooler is one where the receiving-spool is mounted upon anupright revolving shaft and is revolved thereby.

The invention consists in the combination, with the spool-carrying armsof a doublingspooler, of a forked rack-bar, a connected gear-wheel andratchet-wheel, a pawl and its carrying-lever, and a suspended weight forraising the receiving-spool out of gear, alatch and catch for lockingthe pawl-carrying lever against the gravity of the weight,connectinglevers, a sliding sleeve having scalloped rear end, a loosesleeve having scalloped forward end and radial flanges and slidinghook-pins, and a brake-lever, whereby the dropping of a hook-pin willthrow the receiving-spool out of gear and stop the motion of said spool,as will be hereinafter fully described.

A represents the frame of the machine. 13 are the spools from'which thesingle threads are unwound, and which revolve upon. stationary spindles0, attached to a bar of the frame A. From the spools B the threads passsingly through hooks formed upon the upper ends of the pins D, and arebrought together and pass through the slotted guide-arm E, attached tothe traverse-bar F, which is operated in the ordinary manner. These pinsD are mounted loosely in bearings in the frame A in rear of the spoolsB.

The mechanism for operating the traversebar F is not shown in thedrawings, as there is nothing new in its construction. From theguide-arm E the doubled thread passes to and is wound upon thereceiving-spool G, which rests upon and is revolved bythe corrugatedcylinder H, attached to the shaft I. The shaft I revolves in bearingsattached to the frame A, and receives motion by a belt and pulleys fromany convenient motor.

The receiving spool G is placed upon a spindle, J, the ends of whichrest in slotted bearings in the outer parts of the arms K. The innerends of the arms K are pivoted to supports L, attached to the frame A bya rod, M, or other equivalent means.

To the outer ends of the arms K are pivoted the upper ends of the prongsof the forked upper end of the rack-bar P, which passes down through akeeper, Q, attached to a bar of the frame A. The teeth of the rackbar Imesh into the teeth of a small gearwhcel, R, which revolves upon aspindle, S, secured at one end to a support, T, attached to a bar of theframe A.

\Vith the gear-whee1R,by means of a sleeve, is rigidly connected aratchet-wheel, U, with the teethof which engages the pawl V, pivoted tothe upper end of a short lever, W, the

latter being pivoted to the free end of the spindle S, where it is keptin place by a pin, collar, or other equivalent means.

To the lower end of the lever WV is attached the upper end of a cord, X,which passes over a pulley, Y, pivoted to a support, Z, attached to abar of the frame A.

To the lower end of the cord X is attached a weight, a, of a sufficientgravity to draw the lower end of the lever NV inward, and cause the pawlto turn the ratchet-wheel U and gear-wheel R, which raises the rack-barP and the arms K, raising the spool G out of contact with the corrugatedcylinder H.

To the outer side of the lower end of the leverW is attached a spindle,b, to which is pivoted a latch, c. The latch c is made with a shoulderto engage with a catch, (1, attached to a bar of the frame A, to whichbar is pivoted the angle of an elbow-lever, e, in such a position thatthe upper arm of the said lever will rest beneath the latch 0, so aswhen the said lever is operated to raise the latch 0 from the catchd-and allow the weight a to raise the spool G out of contact with thecorrugated cylinder H. Against the lower arm of the elbow-lever e reststhe upper arm of the lever f, which is pivoted to a bar of the frame Ain such a position that its lower arm will rest against or close to theside of the shaft 9 and close to the end of a sleeve, h, placed upon theshaft g,and connected with the said shaft by a tongue and groove orother suitable means, so that the said sleeve will be carried around byand with the shaft 9, and can have a longitudinal movement upon the saidshaft. The lower end of the lever f is held against the end of thesleeve h by a spring, f, connected with the lower arm of the said lever.The shaft 9 revolves in bearings attached to the frame A, and is drivenby a belt, 5, and pulleys j from the shaft I. The rear end of the sleevehis scalloped, to correspond with the correspondingly scalloped forwardend of the sleeve Z, placed loosely upon the shaft 9, and held fromsliding rearwardly upon the said shaft by a collar secured to the shaftor by a stop attached to a bar of the frame A, or by other equivalentmeans. The stop referred to as the equivalent of the collar may be a pinsecured to the bar of the frame A above or near the shaft and projecting across the rear end of the sleeve, to prevent the sleeve frombackward movement. Upon the sleevel are formed three or morelongitudinal radial flanges, m, as shown in Figs. 2 and 4. The flangedsleeve Z m is placed directly below the hook-pins D, as shown in Figs. 1and 2. The threads, in passing from the spools B to the hook-pins D,pass over a guide-rod, n, attached to the frame A, and placed at ahigher level than the hooks of the said pins D, so that the saidthreads, when the machine is in operation, will exert a strain to holdthe said hook-pins raised, as shown in Figs. 1 and 2. WVith thisconstruction, when one of the threads breaks the hook-pin D supported bythe said thread drops, so that its lower end will be struck by a flange,an, of the sleeve Z, and the said sleeve will be stopped and held fromrevolving, and the scallops upon its forward end will push the sleeve hforward, operating the levers f e, and disengaging the latch c from thecatch (1, when the gravity of the weight a will move the lever WV, andcause the pawl V to operate the ratchetwheel U and gear-wheel R, raisingthe rackbar I, and raising the spool G out of contact with thecorrugated cylinder H. As the lower end of the lever WV is drawn back bythe gravity of the weight a, the spindle b or a small roller, 0, placedupon the said spindle, will be drawn against the lower end of the lever19, pivoted to a support, q, attached to the frame A, and will force thebrake-shoe 1", formed upon or attached to the upper end of the saidlever 19, against the flange of the receivingspool G', to stop the saidspool and prevent a single thread from being wound upon the said spool.

It will be observed that as the spool G fills it rises, raising therack-bar P,and turning the gear-wheel R and ratchet-wheel U, withoutaffecting the position of any other part of the machine. The main shaftI continues to revolve after the receiving-spool has been disengagedtherefrom.

ln order to reset the parts to cause the corrugated drum to rotate thereceiving-spool, the latch c is pulled forward and pressed down toengage the stop d, or the upper part of lever \V may be pushed backward.This will allow the rack and receiving-spool to lower by gravity, andwill cause the brake to swing away from the flangeon saidreceiving-spool G, when the drum H, which revolves continually with theshaft I, will rotate said spool G and cause the winding to begin again.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination, with the arms adapted V to carry thereceiving-spool, of the forked rack 1?, spindle S, the gear-wheel It,the ratchetwheel and pawl U V, the pawl-carrying lever W, cord X, pulleyY, and the weight a, substantially as herein shown and described,whereby the said spool can be raised by the gravity of the said weight,as set forth.

2. The combination, with the arms adapted to carry the receiving-spooland the rack connected to said arms, of the spindle S, gearwheel R, andratchet U, connected together and loosely mounted on said spindle,leverW, pivoted on spindle S, pawl V, pivoted to the upper end of said leverand engaging the ratchet-wheel, latch c at the lower end of said lever,catch cl, and mechanism connected with the lower end of said lever,opposite thesaid latch,for drawing the lower end inward, substanti allyas set forth, whereby when the latch is released and the lower end ofthe lever moved inward the upper end of the lever and its pawl will beforced outward to turn the ratchet-wheel and raise the rack and thereceiving-spool connected thereto, as described.

3. The combination, with the lever-locking latch c, of the levers cf,the shaft the sliding sleeve h, having scalloped rear end, the loosesleeve Z, having scalloped forward end and radial flanges m, means forpreventing the sleeve 1 from longitudinal movement, and the hook-pins D,substantially as herein shown IIO 310,722 :&

and described, whereby the said latch will be disengaged automaticallyby the dropping of a hook-pin, as set forth.

4. The combination, with the weight a, cord X, pulley Y, shaft S,pawl-carrying lever NV, and spindle b, of the brake lever 19, having abrake, substantially as herein shown and described, whereby the movementof the said pawl-carrying lever to raise the receiving-spool will applythe brake to the said spool, as set forth.

5. The combination, with the spool-carrying arms K, of the forkedrack-bar P, the gearwheel R, the ratchet-wheel and pawl U V, thepawl-carrying lever W, and the cord X, pulley Y, spindle S, and weight afor raising the receiving-spool, the latch and catch 0 d for locking thelever W against the gravity of the weight a, the levers e f, shaft g,the sliding sleeve h, having scalloped rear end, the loose 2o sleeve Z,provided with means for preventing its longitudinal movement, and havingscalloped forward end and radial flanges m, the hookpins D, the lever1), and brake r, substantially as herein shown and described, wherebythe 25 dropping of a hook-pin will throw the receiving-spool out of gearand stop the motion of the said spool, as set forth.
